A Game-Theoretic Framework for Measuring and Explaining Metric Compatibility in Fair Machine Learning

ICML 2026poster

Machine learning fairness research documents trade-offs but lacks quantitative frameworks to measure intrinsic metric compatibility without requiring causal graphs. We introduce a game-theoretic framework that decomposes metrics into interaction vectors, enabling compatibility measurement between me…

SEF-MAP: Subspace-Decomposed Expert Fusion for Robust Multimodal HD Map Prediction

ICRA 2026poster

High-definition (HD) maps are essential for autonomous driving, yet multi-modal fusion often suffers from inconsistency between camera and LiDAR modalities, leading to performance degradation under low-light conditions, occlusions, or sparse point clouds. To address this, we propose SEF-MAP, a Subsp…
